    I have the worst professor I've ever had for Intermediate Micro. Unfortunately, the textbook (the same Varian one everyone seems to use for this class) doesn't do a great job explaining things either. I've been struggling to find any resources to help me, but this was one of the first times I've understood what was happening. I can't believe how simple this is. Thank you!

    Another way to solve this problem is by use of Cramer's Rule.
    This is done by simplifying the equation. In this case,
    100-40=60
    Firm 1 = 60-2q1-q2
    Firm 2 = 60-q1-2q2
    Use Cramer's rule.
    (-2*-2) - (-1*-1) = 3
    (60*-2) - (60*-1) = -60
    -60/3 = 20 (drop the negative in this case)
    Thus 20 is the equilibrium

    With the collusion outcome, we solve for the monopoly profit-max. output level and price. We will assume the two firms produce half the market output. Here's the math:
    P= 100 - Q. Now solve for total revenue to get TR = 100Q - Q^2. Taking the derivative of TR gives marginal revenue which equals MR = 100 - 2Q. Set MR equal to marginal cost. Because total cost = 40Q, MC = 40
    MR = MC
    100 - 2Q = 40.
    Solve for Q.
    Q = 30 (each firm produces 15 units of output)
    P = 100 - Q = 100 -30 = $70

    Assuming two players in the market, with the assumption that each control half of the market initially with their main target being output maximization, Suppose Q=90-P, with necessary illustrations, (a) Determine market Equilibrium under oligopoly. (b) Given the functions, P= 100-0.5(X1+X2) and cost functions described by C1 = 5X1 and C2 = 0.5X22
    a) Find the profit made by each firm if equilibrium under oligopoly is achieved
    b) Calculate the MR of each firm at equilibrium

    Here is a quick question how to get 3/4q1 and also suppose the two firms are to merge.The department of justice will only permit them to merge only if it is convinced that the price of the product will not be higher than the Pre-merger price.The post merger cost function is of the form c(Q)=XQ.
    Determine the value(s) of X for which the Justice department will deny them the merger.

      It doesn't matter brother, you just substitute the MC for your new firm, the way it's written on my questions is the costs are written as C sub i, where i stands for a specific firm (in this case 1 or 2).

    Yes, if you are told that marginal cost of producing the goods for both firms is 2Q, then the marginal cost for firm 1 is MC = 2Q1 and the marginal cost for firm 2 is MC = 2Q2.

    4 quick questions:
    a) if n No. of firms and n different MC, we should indicate so while solving n equations, right?
    b) if we did know the amount the other producer would supply, would that be like a price leadership problem, where total demand minus its supply is the other's D, right?
    c) is this not equivalent to Nash equilibrium? LIke the least bad option considering any amount the other might produce?
    d) D'u have vids on price bundling?
    Thanks.
